I was looking for some info on the Tyga exhaust I've seen posted online, and found a few youtube videos by monkeytuningfr. The ones that were really interesting in comparison were the ones that show a test ride on a stock msx and then on the same bike after changing the exhaust to the Tyga slip on. The speedo definitely goes over 105 km/h on both videos. Not sure how much boost the slip on gives it, but it does sound better. Could the speed difference be something that is explained by restrictions on US bikes due to emissions standards? Or maybe just a broken in motorcycle vs one fresh out of the crate? Either way, think I'm getting the exhaust.
